Queen are a British rock band formed in London in 1971 and are one of the most commercially successful musical acts of all time. The group originally consisted of Freddie Mercury, (lead vocals), Brian May (lead guitar, vocals), John Deacon (bass guitar), and Roger Taylor (drums, vocals). Queen's initial works were chiefly heavy metal orientated, however with time the band incorporated diverse and innovative styles in their music, exploring the likes of vaudeville, progressive rock, and even funk. Throughout the 1970s, Queen disclosed the absence of synthesisers on their albums, yet their style continued to evolve. They eventually moved away from said approach in the 1980s, reflecting their experimental approach to music.
Brian May and Roger Taylor had been playing together in a band named Smile.
